"The Hero," from Ben Silverman's Electus, is set for a January launch.

Tentatively titled The Hero, from Ben Silverman's Electus and 5x5 Media, it's a new reality competition series that will set out to find the next great hero. Johnson has been tapped to host the eight-episode series and will executive produce with producing partner Dany Garcia.

Slated for a January premiere, The Hero will bring 10 ordinary people together in a house and then assign them various missions that will test their brains, their brawn and even their morality. The show will challenge the competitors to prove they've got what it takes to be heroes, pushing them to the limits to see what they are willing (and able) to overcome, undergo or sacrifice for the sake of their fellow contestants.

The new reality series, which joins cable-mate The Great Escape, will actively include social media into the show's DNA. Each week, viewers will vote for the contestant they deem "most heroic."

"The Hero is a great fit for TNT's drama fans, whether they enjoy stories with a lot of action, suspense and danger or stories that offer inspiration through the heroic actions of everyday people," said Michael Wright, president, head of programming for TNT, TBS and Turner Classic Movies. "We're also very excited about the extensive social-media aspect of The Hero, which will engage viewers on an entirely new level and develop a strong emotional investment in the competitors and challenges."

Johnson will appear in upcoming films G.I. Joe: Retaliation, Pain & Gain, Empire State and the sixth installment in the Fast and Furious franchise. He has appeared in Journey 2: Mysterious Island, Fast Five and The Other Guys. On the television side, Johnson has guested on Family Guy and Saturday Night Live and appeared on WWE Monday Night Raw.

The Hero was created by Craig Armstrong and Rick Ringbakk of 5x5, along with Charles Wachter and Silverman.
